SIP trunk to Fritzbox


Recommended Posts

The setup is the following:
- Fritzbox 7490 as Internet router on, sip port 5060
- Vodia installed on RPi on the internal LAN on, sip port 5065
- Need to connect Vodia to Fritzbox via SIP-trunk

Defined an account/pwd on the Fritzbox for the Vodia, but registration fails w/ error 408 (no response). Pretty sure that the default SIP parameters are incorrect, as we had the same problem with the 3cx-product. Two SIP parameters (‘To : User Part’ and ‘From : User Part’) had to be changed form original caller-id to "AuthID". The log extract below confirms a proble w/ the From- and To-fields. Does anybody know where and how to edit these parameters in the SIP trunk configuration ?

The log shows:

SIP/2.0 400 Illegal request uri
Via: SIP/2.0/UDP;branch=z9hG4bK-69a8e8c39e0e9ea31d63fc58ad424e08;rport
From: <sip:missing>
To: <sip:missing>;tag=badrequest

We used the trunk template "others" as the one provided for the Fritzbox (in v65) apparently doesn't work (see description in the pdf attached). There must be some parameters missing in that template.

By the way, regarding the missing Fritzbox screenshots, we can provide them to you if you specify which ones you'ld like. (We know the Fritzbox config is ok as it works with another 3cx lab-system 🙃)
